Product details
Overview
P6SMB130CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 130 V standoff voltage (VWM), 179 V maximum clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects sensitive ICs and MOSFETs in automotive and industrial power rails against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the P6SMB130CAHE3_B/I datasheet, P6SMB130CAHE3_B/I pinout, P6SMB130CAHE3_B/I application, or P6SMB130CAHE3_B/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM) across temperature.
The device delivers 600 W peak pulse power handling under standardized 10/1000 μs transients while maintaining clamping voltage ≤179 V at 3.4 A - critical for safeguarding 120–150 V nominal systems such as automotive 48 V architectures and industrial DC bus interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for 120 V DC systems. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 179 V at IPPM = 3.4 A - Peak voltage seen by protected circuit during worst-case transient; enables safe margin below 200 V IC ratings. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients per IEC 61000-4-5 Level 4 (4 kV, 2 Ω source) without degradation. |
| TJ max | 150 °C - Enables reliable operation in under-hood automotive environments and enclosed industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per JESD22 standards. |
| Package | SMB (DO-214AA) - Standardized SMT footprint with 5.0 mm × 5.0 mm copper pads; compatible with IPC-7351B land pattern. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; both ends function identically in reverse-biased operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals serve as interchangeable surge current entry/exit points; no orientation required during placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, differential buses (e.g., CAN FD, RS-485), and floating power domains without external polarity management. |
| 600 W peak pulse rating (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial equipment and automotive ECUs up to Level 4. |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive applications including engine control, ADAS power supplies, and body electronics requiring long-term field reliability. |
| Glass passivated junction | Ensures stable VBR over lifetime and temperature (-65 °C to +150 °C), minimizing parameter drift in harsh environments. |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free reflow profiles without preconditioning; eliminates moisture sensitivity handling constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA-E3/5B | Same VWM (111 V), lower PPPM (400 W), SMA package (smaller thermal mass, higher RθJA). | Limited to lower-energy transients; not AEC-Q101 qualified. | Select when cost or board space is prioritized over automotive qualification and 600 W surge headroom. |
| SMCJ130CAHE3_A/H | Same VWM and AEC-Q101 qualification, but SMC package (higher thermal mass, 1500 W PPPM, larger footprint). | Used where higher surge endurance is required, e.g., main battery input in EV charging modules. | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 or sustained repetitive stress is expected. |
Compared with SMAJ130CA-E3/5B, P6SMB130CAHE3_B/I provides 50 % higher surge power rating and automotive qualification; versus SMCJ130CAHE3_A/H, it offers identical protection performance in a 30 % smaller footprint, optimizing PCB area in space-constrained ECUs and IoT edge nodes.

FAQ
What is the clamping voltage of P6SMB130CAHE3_B/I at its rated peak pulse current?
The P6SMB130CAHE3_B/I has a maximum clamping voltage (VC) of 179 V at its specified peak pulse current (IPPM) of 3.4 A under a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that protected circuitry will not experience voltages exceeding 179 V during standardized surge events - a critical parameter for ensuring compatibility with 200 V-rated components downstream of the P6SMB130CAHE3_B/I.
Is P6SMB130CAHE3_B/I suitable for automotive applications?
Yes, P6SMB130CAHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" and "_B" suffixes in its full part number. It has undergone rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation per JESD22 standards. The P6SMB130CAHE3_B/I is explicitly recommended for under-hood and chassis-mounted automotive modules where ambient temperatures reach 125 °C and surge immunity must meet ISO 7637-2 and ISO 16750-2 requirements.
How does the bidirectional configuration of P6SMB130CAHE3_B/I affect PCB layout?
The bidirectional nature of P6SMB130CAHE3_B/I eliminates polarity constraints during placement: no cathode band marking is present, and either terminal may connect to either side of the protected line. This simplifies layout for differential signals (e.g., CAN, RS-485) and AC-coupled rails, reduces assembly errors, and allows reuse of the same footprint across unidirectional and bidirectional variants in modular designs - all while maintaining identical electrical protection performance for the P6SMB130CAHE3_B/I.
What is the thermal resistance of P6SMB130CAHE3_B/I, and how does it impact power derating?
P6SMB130CAHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. At ambient temperatures above 25 °C, its 5.0 W steady-state power dissipation (PD) must be linearly derated - for example, to ~3.5 W at 75 °C ambient. This derating directly affects long-term reliability in sealed enclosures and must be accounted for in thermal modeling of the full system using the P6SMB130CAHE3_B/I.
Can P6SMB130CAHE3_B/I replace older P6SMB130CA parts in existing designs?
Yes, P6SMB130CAHE3_B/I is a direct replacement for legacy P6SMB130CA parts with E3 or M3 suffixes, retaining identical electrical specifications, SMB package dimensions, and soldering profile compatibility. The "HE3" and "_B/I" suffixes add AEC-Q101 qualification and 13" tape-and-reel packaging (3200 units/reel), making the P6SMB130CAHE3_B/I drop-in compatible for automotive redesigns while supporting high-volume SMT production without layout or firmware changes.
